On the third floor of the Hynes Convention Center in Boston, visitors to the Penny Arcade Expo East get to visit an actual arcade, filled with free-to-play arcade cabinets and pinball machines, just like mother used to make.

Okay, technically my mother didn't make arcade machines, but back when I was a kid she'd send me to the local 7-Eleven with two dollars and instructions to get her a pack of Virginia Slim Menthol Lights, keep the change. That change would go towards a Slurpee, with the remainder going into machines just like these.

Well, just like these with cigarette burns and colorfully stick Slurpee syrup stains.
